The plot thickens. Apparently someone is advertising a 6to4 prefix  
somewhere, probably on another wlan, and your system retains that  
address which obviously won't work on an IPv6-only network.

Try turning off your wireless and then turning it on and making sure  
that you immediately go to the IPv6-only wlan.

ping6 fe80::20b:bfff:fea9:7054%en1

should work on the v6-only wlan regardless, though. (This is the link  
local address for the router there.)
